Description

Изобретение относится к области ^станкостроения, а конкретнее к автоматам для одновременной обработки деталей с двух сторон.The invention relates to the field of machine tools, and more particularly to automatic machines for the simultaneous processing of parts from two sides.

Известны автоматы для снятия фасок на торцах цилиндрических деталей, включающие станину, шпиндельные головки, установленные с возможностью перемещения навстречу друг к другу^1].Known machines for chamfering at the ends of cylindrical parts, including a bed, spindle heads mounted with the ability to move towards each other ^ 1].

Недостатком известных автоматов , является необходимость перенастройки режущих инструментов при обработке деталей различной длины.A disadvantage of the known machines is the need to reconfigure the cutting tools when machining parts of various lengths.

Цель изобретения - расширение ₍ технологических возможностей путем обеспечения обработки деталей с отклонениями по длине.The purpose of the invention is the expansion ₍ technological capabilities by providing processing of parts with deviations in length.

Для этого автомат снабжен кареткой, несущей шпиндельные головки и установленной на станине с возможностью возвратно-поступательного перемещения вдоль оси обрабатываемой детали .For this, the machine is equipped with a carriage carrying spindle heads and mounted on the bed with the possibility of reciprocating movement along the axis of the workpiece.

На фиг. 1 представлен автомат, общий вид; на фиг. 2 - разрез А-А на фиг.1.In FIG. 1 shows a machine, a general view; in FIG. 2 - section aa in figure 1.

На чертежах обозначены станина 1, шпиндельные головки 2, каретка 3, обрабатываемая деталь 4, пружина 5, гидроцилиндр 6, датчик усилий 7, бункер 8, гидроцилиндр 9, гнездо 10 ползуна 11 и неподвижная базирующая призма 12.In the drawings, a frame 1, spindle heads 2, a carriage 3, a workpiece 4, a spring 5, a hydraulic cylinder 6, a force sensor 7, a hopper 8, a hydraulic cylinder 9, a socket 10 of the slider 11 and a fixed base prism 12 are indicated.

Устройство работает следующим образом.The device operates as follows.

Из бункера 8 деталь 4 попадает в гнездо ползуна. Затем от гидроцилиндра 9 ползун 11 с деталью 4 поступательно перемещается в направлении неподвижной базирующей призмы12. При этом деталь 4 зажимается.From hopper 8, part 4 enters the slider's nest. Then, from the hydraulic cylinder 9, the slider 11 with the part 4 is translationally moving in the direction of the stationary base prism 12. When this part 4 is clamped.

Затем начинают сходиться шпиндельные головки 2. Если один из режущих инструментов коснется обрабатываемой поверхности раньше другого (при погрешности установки детали 4 в продольном направлении), то инструмент | начнет отжиматься от обрабатываемой поверхности за счет того, что каретка 3 обладает возможностью возвратно-поступательного движения вдоль оси детали 4 под воздействием силовых 5 факторов и пружин 5, укрепленных на торцах каретки 3. Вследствие этого происходит перемещение всего механизма центрирования до тех пор, пока второй инструмент не коснется «' режущей кромкой обрабатываемой поверхности детали 4. Когда оба инструмента касаются обрабатываемой поверхности, начинается процесс резания.Then the spindle heads 2 begin to converge. If one of the cutting tools touches the workpiece before the other (with an error in setting the part 4 in the longitudinal direction), then the tool | begins to wring out from the surface being treated due to the fact that the carriage 3 has the ability to reciprocate along the axis of the part 4 under the influence of force 5 factors and springs 5 mounted on the ends of the carriage 3. As a result, the entire centering mechanism moves until the second the tool does not touch “” the cutting edge of the workpiece surface 4. When both tools touch the workpiece, the cutting process begins.

процесс продолжается до момента 1 получения фасок нужного размера. Команду на отвод шпиндельных головок 2 гидроцилиндрам 6 дают датчики усилий 7 >. которые срабатывают при достижении определенного усилия.реза- ₂ния, соответствующего определенному снятому слою металла.the process continues until the moment 1 obtain the chamfers of the desired size. The command to retract the spindle heads 2 to the hydraulic cylinders 6 is given by force sensors 7>. which are triggered when a certain force is reached. Cutting ₂ corresponding to a certain removed metal layer.

Предложенный автомат позволяет снимать одинаковые фаски с деталей,The proposed machine allows you to remove the same bevel from parts,

Claims

The invention relates to the field of machine-tool construction, and more specifically to machines for simultaneous processing of pulleys from two sides. Machines are known for chamfering on the ends of cylindrical parts including a frame, spindle heads, installed with the possibility of moving towards each other. A disadvantage of the known automata is the need to reconfigure cutting tools when processing parts of different lengths. The purpose of the invention is the expansion of technological capabilities by providing machining of parts with deviations in length. For this, the machine is equipped with a carriage carrying the spindle heads and mounted on the frame with the possibility of reciprocating movement along the axis of the machined part. FIG. 1 shows the automatic, general view; in fig. 2 shows a section A-A in FIG. In the drawings, the frame 1, the spindle heads 2, the carriage 3, the workpiece k, the spring 5, the hydraulic cylinder 6, the force sensor 7 the bunker 8, the hydraulic cylinder 9, the slot 10 of the slide 11 and the fixed base prism 12 are indicated. The device operates as follows. From bunker 8, part k falls into the slot of the ram. Then, from the hydraulic cylinder 9, the slider 11 with part 4 is translationally moving in the direction of the fixed base prism 12. Here, the part C is clamped. Then the spindle heads begin to descend.

2. If one of the cutting tools touches the surface to be treated before the other (with the installation error of part A in the longitudinal direction), then the tool | will begin to be pressed out from the surface to be machined due to the fact that the carriage 3 has the ability to reciprocate along the axis of the part under the influence of force factors and springs 5 fixed on the ends of the carriage

3. As a result, the entire centering mechanism is moved until the second tool touches the cutting edge of the machined surface of part C. When both tools touch the surface to be machined, the cutting process begins. the process continues until chamfers of the desired size are obtained. The command on the removal of spindle heads 2 hydraulic cylinders 6 give force sensors 7. which are triggered upon reaching a certain cutting force corresponding to a certain metal layer. The proposed automaton allows 6 1 identical bevels with parts. 93 1 having length deviations, and its design is significantly simplified. The invention of the chamfering machine at the ends of cylindrical parts, including a bed, spindle heads mounted for movement towards each other, characterized in that, in order to expand technological capabilities by providing processing of parts with length deviations, the machine is equipped with a carriage, carrier spindle heads and mounted on the frame with the possibility of reciprocating movement along the axis of the workpiece.
